Abstract: PURPOSE: To make responsiveness high by alternately applying the voltages of predetermined 2 values to a light bulb element comprising a cholesteric-nematic phase transition type liquid crystal.  
     CONSTITUTION: Transparent electrodes 11', 12' are coated on the transparent substrates 11, 12 of a liquid crystal light bulb element 1, and a liquid crystal layer 13, an inductive body mirror 14, a light shielding film 15 and a CdS photoconductor layer 16 are provided therebetween.

From a driving means 3, AC voltages  V 1  and V 2  are applied at intervals of about 20ms to the transparent electodes 11',  12'. When the information from a write-in means 2 such as CRT display is inputted  to the light bulb element 1, the resistance of the photoconductor layer 16 decreases  in the light irradiated portions and voltage drops becomes small as well. If V 1  is set  high and V 2  low at suitable voltages with respect to the phase transition threshold  value V 0  by taking the resistance of this layer 16 into consideration, the light bulb  element 1 becomes transparent in the light irradiated portions and becomes opaque  in the non-irradiated portions, thus the write-in of high responsiveness may be  accomplished.
